A+6.00 μc point charge is moving at a constant 9.00 ×10^6m/s in the + y-direction, relative to a reference frame.
at the instant when the point charge is at the origin of this reference frame, what is the magnetic field b it produces at the following points?

a) x=0.500m, y=0, z=0
b) x=0, y=-0.500m, z=0
c) x=0, y=0, z=+0.500m
d) x=0, y=-0.500m, z=+0.500m

SOLUTION OF EACH CASES ARE GIVEN BELOW.

Explanation:

We know magnetic field due to a charge q moving with a velocity v .

Case A:

r=0.5i

Putting value of r, q and v .

We get,

Case B:

r=0.5 j

B=0

Case C:

We get,

Case D:

We get , .

answer and explanation;

composition refers to both the types of minerals within a rock and the overall chemical makeup of the rock while texture refers to the size and arrangement of the minerals or grains that make up a rock. both composition and texture can be used to classify rocks, such as igneous rocks. texture describes how the rock became solid or crystallized from liquid, melted rock. composition of a rock describes the minerals that make up a particular rock.
